be generated by any classical system. Can they also recognize and classify patterns that can't be found classically? If class ical data can be encoded in quantum states\, then quantum computers can b e shown to supply exponential speed ups over classical computers for a va riety of standard machine learning techniques\, such as regression\, grad ient descent\, and support vector machines. This talk addresses the use o f quantum computers to perform deep quantum learning\, in which adaptive methods of quantum measurement and discrimination are used to find patter ns in data.

Through careful design of the material's architecture\, new ma terial properties have been demonstrated\, including negative Poisson's r atio\, high stiffness-to-weight ratio and mechanical cloaking. While orig inally the field focused on achieving unusual (zero or negative) values f or familiar mechanical parameters\, more recently it has been shown that non-linearities can be exploited to further extend the design space. In t his talk I will focus on kirigami-inspired metamaterials\, which are prod uced by introducing arrays of cuts into thin sheets. First\, I will demon strate that instabilities triggered under uniaxial tension can be exploit ed to create complex 3D patterns and even to guide the formation of perma nent folds. Second\, I will show that such non-linear systems can be used to designs smart and flexible skins with anisotropic frictional properti es that enables a single soft actuator to propel itself. Finally\, I will focus on bistable kirigami metamaterials and show that they provide an i deal environment for the propagation non-linear waves.

The minimal model program (MMP) is an ambitious program that aims to classify algebraic varieties. According to the MMP\, there are 3 building blocks: Fano varieties\, Calabi-Yau varieties and varieties of general type which are higher dimensional analogs of Riemann Surfaces of genus 0\,1 or at least 2 respectively. In this talk I will recall the gen eral features of the MMP and discuss recent advances in our understanding of varieties of general type.

But there is no consensus on what it would mean to actually solve this problem. In this colloquium\, I propose that turb ulence is most fruitfully regarded as a problem in non-equilibrium statis tical mechanics\, and will show that this perspective explains turbulent drag behavior measured over 80 years\, and makes predictions that have be en experimentally tested in 2D turbulent soap films. I will also explain how this perspective is useful in understanding the laminar-turbulence tr ansition\, establishing it as a non-equilibrium phase transition whose cr itical behavior has been predicted and tested experimentally. This work connects transitional turbulence with statistical mechanics and renormali zation group theory\, high energy hadron scattering\, the statistics of e xtreme events\, and even population biology.\n\nFaculty host: Michael Rub instein\n\nCoffees and cookies will be available before the talk in Physi cs room 130.

Grothendieck showed that the de Rham cohomology of X can be computed using only polyno mial differential forms on X. This observation was the starting point for the theory of algebraic de Rham cohomology\, which has proved to be a us eful invariant for algebraic varieties over an arbitrary field k. In the case where k has positive characteristic\, Berthelot and Grothendieck int roduced a refinement of algebraic de Rham cohomology\, known as crystalli ne cohomology. In this talk\, I will review the theory of algebraic de Rh am cohomology and sketch an elementary construction of crystalline cohomo logy\, based on recent joint work with Bhargav Bhatt and Akhil Mathew.

But there is no consensus on what it would mean to actually solve this problem. In this colloquium\, I propose that turbulence is most fruitfully regarded as a problem in non- equilibrium statistical mechanics\, and will show that this perspective e xplains turbulent drag behavior measured over 80 years\, and makes predic tions that have been experimentally tested in 2D turbulent soap films. I will also explain how this perspective is useful in understanding the lam inar-turbulence transition\, establishing it as a non-equilibrium phase t ransition whose critical behavior has been predicted and tested experimen tally. This work connects transitional turbulence with statistical mecha nics and renormalization group theory\, high energy hadron scattering\, t he statistics of extreme events\, and even population biology.\n\nFaculty host: Michael Rubinstein\n\nCoffee and cookies will be available before the event in Physics room 130.

The journey therefore starts by introducing the genera l concept of effective field theories. I will provide several examples of how such effective field theories are used nowadays to make precise pred ictions for observables at the Large Hadron Collider. I will then continu e our trip by explaining how effective field theories help predict observ ables involving a large number of final state particles\, using tools com monly referred to as parton showers.

She used data t aken with a cyclotron in order to discover the nuclear shell model. Since then particle accelerators have come a long way. Many of the big discove ries in the 20th century involved one kind of accelerator of another. Pre sently we are sitting at the highest center of mass energy collider of al l time\, the Large Hadron Collider at CERN\, ringing in at 13 TeV. A num ber of key advances in accelerator physics were involved. At the LHC we are interested in the lifetimes of particles\, potentially new particles not described by the Standard Model.

At the same time for any \n(arb itrarily small) angle on the plane there exist non-constant \nharmonic fu nctions that are bounded everywhere outside this angle.\nThe situation is completely different for discrete harmonic functions \non the standard s quare lattices. The following strong version of the \nLiouville theorem h olds on the two-dimensional lattice.

Apologies for any inconvenie nce. **\n\n"Advances in the Current and Future X-ray Sources"\n\nX-rays f rom synchrotron radiation (SR) and free-electron lasers (FELs) have huge impact in the recent advances in various areas of science and technology. Having gone through several generations of development\, research facili ties based on SR are currently at the 4th generation stage\, thus referre d to as 4GSRs. A 4GSR employs spontaneous radiation from undulators insta lled in an "ultimate storage ring"\, in which the phase space area of the electron beam is "diffraction limited" in the soft X-ray spectrum. In an FEL\, an electron bunch can exchange energy with a radiation pulse co-pr opagating in an undulator\, giving rise to radiation amplification. With the advance in the linac technology for bright electron beams\, an X-ray FEL (XFEL) became feasible in which the spontaneous emission is self-ampl ified in a long undulator by a factor about a million\, giving rise to in tense\, quasi-coherent X-ray pulse. The brightness of this "self-amplifie d-spontaneous emission" (SASE) is about the same as that of 4GSRs. We are about to witness the advent of XFELs driven by super-conducting RF (SCRF ) linacs with a repetition rate higher by three to four orders of magnitu des than that from Cu-linacs\, and proportionally higher X-ray brightness ...

How physicists can help"\n\nMost of us thought that\, with the end of the Cold War and the rise of democracy in Russia\, the danger of a nuclear A rmageddon had receded and what remained was to pilot a glide path to very a low level of de-alerted nuclear weaponry and strengthen the nuclear no nproliferation regime. That did not happen. NATO expanded east\, democra cy faded in Russia\, Russia invaded Ukraine\, nuclear reductions halted\, the US has exited two of the three bilateral nuclear arms control agreem ents it has with Russia and seems on track to exit the third\, and we are in the midst of nuclear proliferation crises with Iran and North Korea.\ n\nGiven this situation\, the American Physical Society has funded a proj ect to get physicists engaged with nuclear threat reduction again. The p urpose of this talk is to provide an overview of the current situation an d the various proposals that are being debated to mitigate the dangers. T he hope is that a few physicists in the audience will consider educating themselves further and then become involved in helping to educate their m embers of Congress. The speaker will be available for discussions before or after with anyone who might be interested.\n\nFaculty host: Phil Barbe au\n\nRefreshments will be available before the event in room 130.\n\nThi s seminar is presented with support from the Consortium for Nonproliferat ion Enabling Capabilities (CNEC) at NC State.

Various insulating top ological phases are known to realize unique electromagnetic couplings suc h as the quantum Hall effect and "axion electrodynamics"\, and understand ing this led to an improved understanding of polarization and magnetoelec tricity in all materials. The main new results are on how the recently di scovered topological Weyl and Dirac semimetals can show unique electromag netic responses. We argue that in linear response the main observable eff ect solves an old problem via the orbital moment of Bloch electrons\, and how in nonlinear optics there should be a novel approximately quantized photocurrent effect. This photocurrent effect should have magnitude deter mined by fundamental constants\, namely the cube of electric charge\, div ided by the square of Planck's constant\, and may have been observed in r ecent experiments.\n\nFaculty host: Thomas Barthel\n\nRefreshments will b e available before the event in room 130.

Her Democratic Progressive Party has attempted to recenter Taiwan's focus away from cross-strait co operation towards strengthening economic ties with other East Asian count ries. This marks a departure from Taiwan's previous platform\, developed by the rival Kuomintang Party\, that emphasized friendlier relations with the mainland. Across the strait\, China's President Xi Jinping has respo nded to Tsai's gradual decoupling with increased military demonstrations and more aggressive rhetoric. President Biden\, meanwhile\, has opted to continue the Trump-era prioritization of great power competition with Chi na by increasing support for the island. \n\nTo better understand each ac tor's motivation\, their goals for the relationship\, and the short and l ong-term future of the region\, join the Alexander Hamilton Society for a panel discussion featuring Ian Easton from the Project 2049 Institute an d Emily Feng from NPR.\n\nThe event will take place in a hybrid format wi th one of the panelists in person and the other joining us via zoom.

CREATED:20221117T161636Z DESCRIPTION:This talk starts by reviewing known examples of how topologica l materials generate new kinds of electrodynamic couplings and effects. One category of topological phases can be understood in terms of nearly f ree electrons\, but still manage to show interesting behavior such as the integer quantum Hall effect. We start with known cases and build up to an understanding of how the recently discovered topological Weyl semimeta ls can show unique electromagnetic responses\; in nonlinear optics there should be a new approximately quantized effect\, which may have been seen experimentally. This nonlinear effect has a natural quantum e^3/h^2 and appears in chiral Weyl semimetals over a finite range of frequencies. W e then turn to fractional topological phases and their possible appearanc e in frustrated magnets ("spin liquids"). Emerging computational techniq ues allow a nearly unbiased comparison of spin liquid candidates in the o riginal model studied by Anderson\, the triangular lattice Hubbard model\ , and analytical methods help understand intuitively why a particular kin d of topological spin liquid is an attractive candidate. We close with s ome comments on the remarkable recent progress in using quantum computers and emulators to create topological states.

CREATED:20230216T195725Z DESCRIPTION:Measurement of the highly redshifted 21 cm emission line from neutral hydrogen has the potential to revolutionize our understanding of the universe's evolution. These measurements would map the universe's str ucture during the Dark Ages\, Cosmic Dawn\, and Epoch of Reionization\, w hen stars and galaxies first formed and ionized the intergalactic medium. They would reveal the effect of Dark Energy throughout cosmic history\, probe the dynamics of early galaxy evolution\, and constrain Dark Matter interactions. However\, 21 cm cosmology experiments have not yet overcome the challenges that will allow them to achieve their potential.

CREATED:20230216T220119Z DESCRIPTION:The Event Horizon Telescope (EHT) has produced images of radia tion from relativistic plasma very close to the horizons of two supermass ive black holes\; in the Galactic Center Sgr A* and M87. In this talk\, I will present the past and future of horizon-scale black hole images: how do we get them\, what have we learned\, and what will they show next? I will first discuss how we reconstruct and validate images from sparse\, d ifficult-to-calibrate EHT data. I will focus on the first polarized imag es of M87*\, which provide the most stringent constraints on a near-horiz on environment. Comparing polarized EHT images with a large library of ma gnetohydrodynamic simulations indicates that the magnetic field near M87* is strong\, ordered\, and dynamically important in limiting accretion an d launching M87's powerful relativistic jet. Finally\, I will show how fu ture observations of M87* with an expanded EHT array will have significan tly improved dynamic range and resolution. These observations will map th e structure and dynamics of plasma and magnetic fields from the central b lack hole out through the jet on larger scales. They may also reveal subs tructure in the strongly-lensed image\, including the black hole's 'inner shadow.' In the coming decade\, new EHT and multiwavelength observations will combine with advances in analysis techniques and simulations to ill uminate the black-hole jet connection\, probe relativistic plasma microph ysics\, and enable new tests of spacetime.

Quan tum phase transitions represent profound shifts in material properties dr iven by quantum fluctuations at absolute zero temperature\, holding the p romise of unveiling novel quantum states. Quantum spin liquids\, on the o ther hand\, are exotic quantum phases where particle spins remain in an e ntangled and disordered state even at very low temperatures\, presenting opportunities for revolutionary applications in quantum computing. Additi onally\, we explore topological phenomena\, which involve unique material behaviors resilient to small perturbations and are characterized by topo logical invariants. Such phenomena hold immense potential for advanced el ectronics and quantum technologies due to their robustness against defect s and disorder. This presentation integrates materials design\, synthesis \, thermodynamics characterization\, and advanced neutron and X-ray scatt ering techniques to unravel the intricate properties of these quantum sta tes\, shedding light on their fundamental physics and their applications in emerging technologies.

Significant chall enges are\, for example\, the understanding and design of high-temperatur e superconductors and systems with topological order. Strong correlations render mean-field and perturbative approaches inapplicable\, and\, for s ome of the most interesting systems\, quantum Monte Carlo is hampered by the notorious sign problem. However\, the investigation of entanglement p roperties shows that typical many-body systems in equilibrium and after l ocal perturbations do not explore the entirety of the exponentially big H ilbert space. This led us to techniques that approximate strongly correla ted states by networks of tensors - so-called tensor network states. We a pply them in studies of condensed matter physics to investigate quantum p hase transitions\, dynamic response\, equilibration and thermalization\, quantum transport\, as well as decoherence phenomena and nonequilibrium t ransitions in driven-dissipative systems.\n\nWhile computation costs of t ensor network methods scale polynomially instead of exponentially in the system size\, classical computation has its limits and it is still diffic ult to assess certain phenomena in 2d and 3d systems with sufficient accu racy. I will discuss our recent efforts to investigate quantum materials using quantum computers. A hybrid quantum-classical solver based on a mul ti-scale entanglement renormalization ansatz (MERA) allows us to study co ndensed matter groundstate problems. Due to causal-cone structures of the MERA tensor network\, one can simulate large systems on noisy intermedia te-scale quantum (NISQ) devices. The number of required qubits is system- size independent and increases only to a logarithmic scaling when using q uantum amplitude estimation to speed up gradient evaluations. Our benchma rk simulations have established a quantum advantage for this approach. I will report on first experimental implementations\, demonstrating a quant um phase transition on ion-trap devices of the Duke Quantum Center\, and shortly comment on the question of barren plateaus.

Indeed\, experiments are underway that use muons as a window to search for new particles or forces. The muon's anomalous m agnetic moment is a particular focus of these efforts because of a longst anding tension between experiment and theoretical expectations. This quan tity is now known with an exquisite precision of 190 parts per billion\, thanks to the g-2 experiment at Fermilab\, which is on track to reach its precision goal of 120 part per billion in the next couple of years. The theoretical calculations of the muon's magnetic moment must account for t he virtual effects of all particles and forces within the Standard Model\ , where effects coming from hadrons\, governed by the strong interactions \, are by far the largest sources of theory uncertainty. Recent estimates of hadronic corrections have created puzzles on the theory side\, which are currently being investigated. I will discuss the ongoing interplay be tween theory and experiment that is essential to unlocking the discovery potential of this effort.

Its neutral charge and astonishingly low mass make its detection\, and therefore its use in fundamental physics laboratories\, exceedingly difficult. Despite this\, it is in the neutrino sector where we have rece ntly seen challenges to the long-standing Standard Model of Particle Phys ics. The neutrino is also an important player and messenger to the physic s that takes place in astrophysical environments and the early Universe-i t is one of the most hopeful windows to New Physics. In this talk\, I wil l discuss a high-risk\, high reward\, multi-decade\, world-wide research program that seeks to answer many of the open questions about the neutrin o. What is the mass of the neutrino? Is there a 4th generation? What are the sizes of the electromagnetic form factors and the effective neutrino charge radius? What can it tell us about neutron skin depth and the equat ion of state of neutron stars? Does it play a role in the rapid process f or the creation of heavy elements? Is lepton number conserved? What can i t tell us about the weak charge? Are there any new force carriers? I will also touch on how these experiments can help search for the putative Dar k Matter in our Universe. These are some of the questions that the LEGEND neutrinoless double beta decay experiment\, and the COHERENT elastic neu trino-nucleus suite of experiments seek to answer over the next 20+ years .
